Study on numerical classification for 34 soil profiles in Chengxian County of Gansu Province was carried out by means of a cluster analysis method of standardized variateoblique distance-sum of square error. Indexes used in numerical classification include soil pH, organic matter (O. M.), total N, totoal P, total K, available P, available K, cation exchange capacity (CEC) SiO_2, Al_2O_3, Fe_2O_3, CaCO_3 and physical clay (<0.01 mm). Results obtained from this study showed that 34 soil profiles used...

Study on numerical classification for 34 soil profiles in Chengxian County of Gansu Province was carried out by means of a cluster analysis method of standardized variateoblique distance-sum of square error. Indexes used in numerical classification include soil pH, organic matter (O. M.), total N, totoal P, total K, available P, available K, cation exchange capacity (CEC) SiO_2, Al_2O_3, Fe_2O_3, CaCO_3 and physical clay (<0.01 mm). Results obtained from this study showed that 34 soil profiles used in the experiment may be divided into five soil groups. From variance analysis for eight main indexes (i.e.pH, O.M., CEC, SiO_2, Al_2O_3, Fe_2O_3, CaCO_3 and clay) of the five soil groups shows that the differences of indexes between soil groups are all significant (F_(0.05)) or very significant (F_(0.05)) respectively except pH, CEC and SiO_2 content. In addition, there are also significant differences between soil groups in geographical distribution, vegetation types and calcareous reaction in fields etc.. Each soil group has its marked genetic characters. Compared with genetic classification system, the five soil groups belong to brown earth, leached drab soil, ortho-drab soil, carbonate drab soil and cultivated fluvioaquic soil respectively.

In this paper, the long—term averaged vector of the LPC reflecting coefficient vector abstracted by the Maximum Entropy Spectral Estimation method is used as the speech feature vector of speakers. The efficiency of the feature vectors and the discrimination of speakers for the purpose of text—independent speaker identification is analyzed using the average within speaker variance funeton, the average between speaker variance fuction and the ratial of average between—within speaker variance ruction defined in this paper. A simplized decision equation——the weighted Euclead space distance sum of feature vectors, which is easy for computing and programming, is conduced from the Bayes decision principle. The reciprocal of the average within speaker variance fundtion isselected as the optional weighting function. A sequencial decison principle for refusing the out—set speakers is presented. A correspondent experimental system related with a microcomputer is implemented. The response time is 3 seconds. The performants of text—independent speaker identification test is carried using this system for the population of 20 speakers. The correct rate of the identification is 95. 41percent, the faulse accept rate is 10. 67percent and the faulse refuse rate is 5. 67 percent.

The best one-variable equations were obtained with GAI for several physicochemical properties of seven pairs of olefin cis, trans isomers. The linear correlation coefficients are in the range of 0.975 to 0.997. GAI was also compared with the other five topological indices, Randic connectivity index x, Wiener number W, Hosoya index Z, the average distance sum connectivity J proposed by Balahan and a_x index introduced...
